I will harden or secure linux server ubuntu debian centos rhel

Your Linux server security is important when running production workloads.

Whether it is a new server or an old one, I can help you improve server security. I have been managing Linux servers for almost a decade. I have taught multiple individuals how to manage and secure Linux servers for years. You are in good company.

Here is a list of things this gig will cover :

1. Update and patch the Linux system.
2. Configure a firewall
3. Disable unused services and ports.
4. Set up SSH key authentication and disable password login.
5. Restrict/disable root login via SSH.
6. Enforce strong passwords and lock user accounts after failed attempts.
7. Install and configure intrusion detection/prevention systems (e.g., Fail2Ban).

Other options you may ask for assistance with:

1. Configure and enforce regular system backups.
2. Audit logs
3. Enable SELinux or AppArmor.
4. Install and enable crowdsec
5. Scan the system for security loopholes and vulnerabilities
